Brunsviga 132z-18


This is a twin Brunsviga calculating machine. The pinwheel lever-set non-printing machine has a metal housing painted black, a metal mechanism, a wooden base, and a metal cover. It consists of two adjacent and interconnected instruments. Each has ten levers for setting numbers, with the number set appearing in a row of windows above the levers. The two result registers are on a single carriage at the front of the machine, and the two revolution registers are in back of the respective levers. The handle for operating both machines extends from the right side. All the registers have zeroing levers and decimal markers.

A mark on the right front carriage reads: BRUNSVIGA-MASCHINENWERKE (/) GRIMME, NATALIS & CO.A.-G. A stamp on the left front gives the model and serial number: BRUNSVIGA 13Z-18 (/) 200118

The cover has three marks: H. T. 243; Hpk. 2; and PROPERTY OF USA -CE-M (/) 7420-111-0018.

This machine came to the Smithsonian from the Department of Chemistry at Bridgewater College in 1972.
